2021 12 14 CNC machining is a manufacturing process that utilizes computer numerical control (CNC) systems to control machine tools. It enables precise and efficient production of complex parts and components. In CNC machines, the movement of the cutting tools is facilitated by rail systems, which guide the motion along a specific axis. Two common types of rail systems used in CNC machining are hard rail and linear rail.

VMT 2021 12 14 Common right-angle grooves in precision CNC machining parts are open, closed and semi-closed. The end of the semi-closed groove has a vertical milling cutter arc (vertical arc) and a disc milling cutter arc ( Horizontal arc) two forms, the keyway on the shaft is a typical right-angle groove that connects the shaft and the sleeve with a flat key.
